Some Cold Performance from CPI Switches
All reports have us in for a cold winter this year, with temperatures here in NJ hoovering around freezing pretty consistently during the day and well below freezing at night. While we’re bundling up to stay warm, it turns out that there are no little wool sweaters for critical electronic equipment, and temperatures inside a cold metal enclosure, or on the exterior of a vehicle can get far worse that. We talk a lot about the true waterproof nature of our pendant switches and their ability to operate in hot, vibrational environments but a long time ago CPI limit switches had to solve the opposite problem: how to keep our contacts from freezing up in cold damp weather well beyond the comfort zone of most switches and humans. Consider a generator deployed on an oil rig in the north Atlantic, or a bulkhead door on the deck of a container ship bound for the South Pole. It took a lot of trial and error, and investigation to develop a switch which we know can reliably operate down to -6...
